Answer:
Step-by-step explanation:
Tn = ar^(n-1)
a = 4, r = 8/4 = 2 for n = 15
T15 = 4 × 2^(15-1)
= 4 × 2^14
= 4 × 16384
= 65536
Answer:
No
Step-by-step explanation:
Use the pythagorian theorm to find whether it's a right triangle or not.
So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared
5.2 squared= 2.4 squared+ 4m5 squared
27.04= 26.01
It's not equal so the triangle isn't a right triangle.
Answer:
1 ten.
Step-by-step explanation:
1 ten = 10 ones/units
First of all, you can move the +2x to the other side:
-11 = -26 - 2x
Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
15 = -2x
Then you can divide both sides by 2:
7.5 = -x
Then you can flip the sides and the signs around:
x = -7.5
No, The answer is not -7, it is -7.5
Hope this helps! :)
